except后接句子吗

比如说 enerything is good except for the weather.

这里能不能用except？

我对于except和except for 一直弄不清楚。。。
请解释一下。谢谢大家！

这里可以用 except
如果except修饰一个名词，一般说来两者可以互换，比如说你句子中的everything.
但在某些情况下只能用expect for不能用except

比如说
(1) The room was entirely empty except for Morris.
这里用except Morris就不太通。
或者
(2）The bus was empty except for me
用except me也不通。

这种情况因为except for Morris（me)在这里是修饰前面那个陈述句的，换的话句子不通。
except for Morris修饰the room was entirely empty
except for me 修饰the bus was empty

比较简单的判断方法是用but在句子中替代except/except for，可以的话就可互换
everything is good but the weather. 可以
the room was entirely empty but Morris. 不可以
the bus is empty but me. 不可以

还有一种方法，你把句子中except/except for的位置挪一下，挪到它所修饰的那个词旁。
everything except the weather is good. 可以
the room except Morris was entirely empty. 不可以
the bus except me was empty. 不可以

因为who shook his head,是定语从句，来修饰这个老头的，所以one old man才是主体要看的，所以except for one old man.而who shook his head是说明了这个老头的状态，而与老人相对比的是，they.
